HIGHLY doubt will be seeing any major update "soon" I bet it will be at least another 9-12 months. I mean new biome appearance/terrain, what 8-15 new mobs/NPCs, different patterns, crafting pieces, POIs, weapons, gear, stations etc etc..

I have only been in ML briefly because my community server is taking things really slow. But it is so gorgeous.. and terrifying all at once I love it. If it takes them a long time to make the next one that beautiful then so be in. lol.
